C# 为自定义日历WPF创建事件/约会

我做了一个自定义的时间表，如下所示，它可以正常工作，但现在我正在尝试添加活动/约会，我一辈子都不知道该怎么做。我希望能够单击日历上的一个按钮（日期），创建约会/事件，然后将事件的标题添加到日历上正确的网格单元格（日期）上为其创建的txtblock（网格单元格）中。我不知道如何通过单击指定的按钮来访问某个gridcell。我对这段代码的编写方式并不感到自豪。我本来想拥有一个MVVM，但现在可以了。我不得不面对的问题是，每当我点击<或>按钮更改月份时，一个新的月份被创建，旧的月份被删除。所以一次只做一个月。请帮忙，谢谢

wpf的一部分：使用ItemsControl

  <ItemsControl.ItemTemplate>

            <DataTemplate>

                    <StackPanel>


                        <Button Content="{Binding day}" Width="175" HorizontalAlignment="Stretch" VerticalAlignment="Top" VerticalContentAlignment="Top" HorizontalContentAlignment="Left" Name="btnCalenderDate" Click="btnCalenderDate_Click" Loaded="btnCalenderDate_Loaded" Height="18" FontSize="10" FontWeight="Bold">

                        </Button>
                        <TextBlock OpacityMask="Black"  Name="txtBlockdays" VerticalAlignment="Top" TextWrapping="Wrap">

                    </StackPanel>
                </DataTemplate>
                
            </ItemsControl.ItemTemplate>


        <!-- ItemContainerStyle -->
